I.Overview
HZJF-9011D partial discharge detector is a new type of digital partial discharge detector developed by our company. It retains the advantages of JF-A01N partial discharge detector, reduces the volume and optimizes the performance. It uses 10.1 inch touch screen to replace the traditional operation mode of oscillograph and physical knob, making it more convenient to use.The instrument adopts full touch screen operation, which not only improves the service life of the operation, but also has the following functions: one key automatic correction; high voltage test voltage divider ratio can be set; serial communication upload test data. The instrument has the characteristics of high sensitivity, wide application range, wide dynamic range of amplification system, multiple frequency band combinations (nine kinds), and strong anti-interference ability. It is a practical partial discharge testing instrument widely used by electric power departments, manufacturers and scientific research institutes.
